文章把实际的分离式热管简化成单一的循环回路，并通过对微元段的分析，建立了一个完整描述分离式热管管内工质流动及换热过程的数学模型。该模型可采用计算机迭代求解，分别采用相应的流动阻力和传热公式计算有关参数。计算的结果和相应的实验结果绘制成一组曲线。该模型对于改进设计和进一步了解分离式热管的特性有实际意义。
The article simplifies the actual separated heat pipe into a single loop, and through the analysis of the micro-section, establishes a mathematical model that completely describes the flow and heat transfer process of the working fluid in the separated heat pipe. The model can be solved iteratively by computer, and the related parameters of flow resistance and heat transfer are calculated respectively. The calculated results and the corresponding experimental results are plotted as a set of curves. This model is of practical significance for improving the design and for further understanding of the characteristics of the split heat pipe.
